Beit known that we, FRANCIS LEINEWEBER and CHARLES WELGE, citizens ofthe United States, residing at San Marcos, in the county of Hays and State of Texas, have invented a new and useful Ealing-Press, of which the following is a specification.

Our invention relates to improvements in hay-presses of the full circle or continuous type for baling hay, straw, and the like.

The object of the invention, considered in its specific aspect, is the production of ua positive trip connection between the power-head and pitman which will exert a powerful leverage during the termination of the stroke and will cause the prompt release of the pitman from the power-head when the plunger has reached the limit of its stroke.

A further and subordinate object is a novel arrangement of the buffer-head and of various structural details throughout. the device.

Referring to the drawings, Figure l is a plan nview of our press complete. Fig. 2 is a side elevation thereof. Fig. 3 is a plan view of the outer end o f the tongue, the powerhead, and a portion of the pitman, hidden parts being shown in dotted lines. Fig. 4 is a similar view with the pitman at one limit of its stroke and in theact of being tripped. Fig. 5 is a detail view of the power-head, and Fig( 6 is a detail view of the end of the pitman.

Fig. 7 is a detail longitudinal section on theplane ,of the line 7 7 of Fig. 1, illustrating the means for arresting the movement of the plunger at the limits of its travel in either direction. Fig.V 8 is a detail horizontal section through the power-head and the camformed end of the pitman, the plane of the section being indicated by the dotted line S 8 of Fig. 2.

Referring to the numerals onthe drawings, 1 indicates the baling-chamber of a hay-press constructed substantially in the ordinary manner, and 2 thenbeam or tongue 'connecting the baling-chamber with the powerfplatform 3, whichsupports the power mechanism of the press. i

Ltindicates the plunger, .movable within the press, to the top ofwhich is bolted a guide land stop-plate 5, beveled at its front end (see Fig. 6) to permit an increasing frictional contact with a transverse stop-roller 6, mountf ed between the sides of the baling-press and having its opposite end 7 extended over a buffer-head 8, carried by spring1etracted bolts 9, passing through the front standard 10 of the baling-chamber. As the plunger is thrown forward in a mann-er to be described the beveled ends of the plate 5is presented to the roller 6 at the limit of its stroke, constituting a gradually-applied stop calculated to limit the stroke of the plunger without undue jar when the press is emptyor practically so. As the plunger is violently retracted by the action of the spring which imparts the rebounding movement to, said plunger the shock is relieved bythe engagement of the stop-plate with the buffer-head within a recess 11, in which the extended end 7 of the plate 5, which is beveled on its under side, is designed to be received.

12 indicates the pitman, pivotally connected to a projection 13, extending from the rear end of the plunger. The opposite or free end of this pitmau is formed with a cam 14, extending from about the center line of the pitman and terminating at its inner end in a coucavity 15 intermediate ofthe cam 14 and a short cam-face 16, terminating at the edge of the pitman adjacent to the power mechanism. This power mechanism in presses of this class comprises a power-head 17, designed to effect the reciprocation of the pitman and to be operated by a sweep 18, continuously movable in a circular path. The power-head 17 is mounted upon a vertical shaft 19, extending upwardly from the power-plate, and it is preferably provided on its under side with a bearing-disk 20, revoluble against the face of a similar disk 2l, supported at the extremity of the beam. The power-head proper is composed of head-plates 22 and 23, intermediate of which extend actuating-pins 24, located adjacent to the opposite ends of the head plate and preferably contiguous to the oppo-V site sides thereof. As the head is rotated one of the pins 24. is presented'tothe concavity 15 and the pitman is urged in a direction to cause the reoiprocation of the plunger;

is arrested by the disengagement of the pitman from the pin, which disengagement of the parts is due to a tripping-cam of the power-headA riding against the cam-fa ce 14 of the pitman at the instant that the laterali'` the headplates22 and 23.

movement of the pitx'nan is arrested by one of the frame-bars 25, which supports the rollers 26,-said framebars and the rollers thus constituting the roller-frame in which the pitman is free to haveanendwise movement and a limited lateral movement.

The utility of the Sunbeam-feesie', extend; ing from the concavityl, is readily apparent,

since-itsgeneral direction is tangenti'al'tothe circular path described by the actuating-pins.

Therefore, asvthelateralmovement ofthe pitman necessary toaccommodate the-movement of`1thev engaged lockiugpin is arrested by theroller-'framecontinued movementof the sweepwill-causelthe pin to advance along'the camsface 16,:1nd the most powerful leverage will therebyzbe exerted to drivethe-plunger under'an enormous pressure throughthe Iilnal fraction-ofits stroke.

As `sliown by'Fig. l of the drawings, one

sidefof'the roller-table lies in a position nearlyin line-with a planewhich lbi'sectsthe-axis of therevoluble po wer-head andthe pitman, and

this sideoffthe frame` provides'a st'opsurface ble head reaches a position toride uponthe shortabrupt'cam-surface 16 at the-end'of the pitman, and thestop=surface on said rollerl framet'huscoact's wi th the pitmanan (l-through the-latter'with thel power-head ina manner'to'` assist' the driving element' ofthe power-head in riding'againstV the abrupt short'cam-su-rface 16; soas to givethe iinal compression thrustto the pitm'an Y and the plunger.

VTheforwardlnovement ofthe plunger is at:

all times resisted by a powerful plungerretracting spring 27, connected at one end to the beam 2"and at its opposite end to the pitman 12, adjacent to the connecting of thellatterwiththe plunger. 28A indicates a'second` spring designed to exert a constant pressure on the-pitman to draw' the latter at all times in theldirection'of the-power-head, one of itsy endsbeingipreferably'connectedy t'o -a'laterall frame 29 and its-,opposite end to the side of* ,4 the pitman.. v Grdi-narily the resistance of` the retracting-spring is so considerable that-'when the shaft of the power-head, the-engagedac# tuatingvpin,.y and the contacting face ofthe pitman extremity are in alinement" thereiis danger of binding the parts, especially as the oli?lv the feedof the material.

highly-compressed bale also exerts a pressure upon the plunger. To overcome this tendency, we have devised the positive trip mechanism, which comprisesthe cam-face 14, extending from the end'of the pitman, and a pair of tripping-cams 30, formed upon-a camblock 31, mounted upon the shaft' between Having described the structural lfeatures of our invention, it maybe well to briefly outline the .operation thereof in order that the VIf'unctonsoi theiseveral partsand the utility of their specialarran gement may be properly 'eonlprehended".

The baling-chamber having been filled with the material to be baled and the `power,.of Whatever form, having` been applied to the sweep; the power=headisrotated and one of the actuating-pins is presenteditothe concavity 15 at" the endiof the, pitman. TheA pitman will now move forward asthe vpin ad- 1 varices and will swing under the] tension of the springv 27 to make. the freeen'dsof the pit- 'ma-n travel in anarcshaped path described I bythe movement ofthe actuating-pin" on the power-head, while said power-headV pin and t'l1epit'man remainy in engagementonelwith theother.

Y As the pin: approaches the longitudinaleccnter of'4 movement. ofj'the plunger furtherlatera movement of. the pitman will v'be prevented bytscOntact with one side of lthe rollerfraineand' the.` pin thereafter advancing alongfthe ,shortv Cam-face 16 of the jnow laterally-immovable pitman will force the latter to-move4 l on,g ;itudi'na1lyunder'great pressure, as already described'. As thej pin approaches the end of the face 16 the tripping'- camwhi'ch follows after the `pinis brought into contact'vwith the cam-face 14, yandl assaid triptping-cam continues to `advance onI said' cam- 'face' 14- the pitman is;forcedz laterallyagainst the-'tension of the spring 27, saidctripping camV thereby eiecti'ngf the disengagementof `the actuatin'gpinfrom thepitman.l The-re-V tractingssprings'will now restore the plunger and pitmanto their normal positions, andthe next operation-ofthese parts will be eiected 'by thepin and cam locatedfatftheside ofthe power-head" opposite the corresponding ele- `ments whose operationV has just` beenl described. As the plunger isadvancedorforced in aforward direction by'an actuating-pin 24 lof the powerhead engaging'withthe" notched and cam-formed'extre'mity'of the pitman 1'2 the beveled front end` of the stop-plate 5" onl the plunger is forced below the roll 6,' which servesA to limit,vin a measure, theA forward movement of' the plunger and to effect the ifoldingof the-material which isbeingffed-into the baling= chamber,v said plate 5 i also cutting As the pow-er- -head continuesto'rotatc and-the notchedand cam-formed end of thepitman is'disengaged Lfro'rn'the actuating-'pin of said power-head by lthe actionof the tripping-cam the spring 27 reacts to retract the rebounding plunger sud- IOO IIO

Alo

denly. During this rebounding movement of the plunger the beveled rear end 7 of the stop-plate 5 rides against the buffer-head 8, the springs 9 of which buffer-head are arranged to resist the travel of the buffer-head with the stop-plate of the rebounding plunger. Hence the'bufter-head operates to check and retard the rebounding movement of the plunger and finally to arrest the same, so as to reduce the jar and shock of the working elements of the press. l y

From the foregoing it will appear that we have devised a simple, powerful, and positively-acting hay-press; butV while the present embodiment appears at this time 'to be preferable We do not desire to limit ourselves to the structural details illustrated and described, but reserve the right to change, modify, or vary suchv details within the scope of the protection prayed.
